Here are a couple citations for that quotation... I hope this helps. BTW: Which video were you referring to, because I've never created any videos, just some graphics... :-)
Let me know when you've got the video up and I'll link to it at YouTube if that's where you're going to publish it...
I personally got it from the CNN.com article. There is also accompanying video at the CNN.com website [See the "video" link with the little camera above the article]
Just FYI - I have a list of several other quotes at my "NObama" Blog - I've got to add more as it's been a while since I worked on that page.
